Estimating catch-at-age by combining data from different sources
(Journal article; Peer reviewed, 2005)Estimating the catch-at-age of commercial fish species is an important part of the quota-setting process for many different species and almost all countries with a fishing fleet. Current procedures are usually very ... -
Diurnal variation in acoustic densities: why do we see less in the dark?
(Journal article; Peer reviewed, 2005)Diurnal fluctuations in total integrated echo abundance and in vertical density profiles were examined using data from the Norwegian combined acoustic and bottom-trawl survey for demersal fish during winter in the ... -
When fish meet a trawling vessel: examining the behaviour of gadoids using a free-floating buoy and acoustic split-beam tracking
(Journal article; Peer reviewed, 2005)The reaction of individual gadoids to a bottom-trawling vessel has been observed in situ in the Barents Sea using a free-floating buoy and acoustic target-tracking methods. More than 20 000 tracks were analysed in terms of ... -

In situ swimming speed and swimming behaviour of fish feeding on the krill Meganyctiphanes norvegica
(Journal article; Peer reviewed, 2005)In situ swimming speed and swimming behaviour of dielly migrating planktivorous fish were studied at a 120-m-deep location. Acoustic target tracking was performed using a hull-mounted transducer and submersible ... -

Evaluation of potential reference genes in real-time RT-PCR studies of Atlantic salmon
(Journal article; Peer reviewed, 2005)Background Salmonid fishes are among the most widely studied model fish species but reports on systematic evaluation of reference genes in qRT-PCR studies is lacking. Results The stability of six potential reference ... -
Timing and determination of potential fecundity in Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2005)Studies using annual averages of lipid storage or estimated quality of the feeding season have shown that energy reserves influence egg production in Atlantic cod (Gadus morhua). However, vitellogenesis starts months ... -
Protocols for calibrating multibeam sonar
(Journal article; Peer reviewed, 2005)Development of protocols for calibrating multibeam sonar by means of the standard-target method is documented. Particular systems used in the development work included three that provide the water-column signals, namely ... -

Relative transcript quantification by Quantitative PCR: Roughly right or precisely wrong?
(Peer reviewed; Journal article, 2005)When estimating relative transcript abundances by quantitative real-time PCR (Q-PCR) we found that the results can vary dramatically depending on the method chosen for data analysis. -
Assessing changes in age and size at maturation in collapsing populations of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2005)By estimating probabilistic reaction norms for age and size at maturation, we show that maturation schedules of Atlantic cod (Gadus morhua) off Labrador and Newfoundland shifted toward earlier ages and smaller sizes ... -
Picoeucaryot alga infecting blue mussel Mytilus edulis in southern Norway
(Journal article; Peer reviewed, 2005-01-25)During summer 2001, blue mussels Mytilus edulis with abnormal shell growth were collected near Kragerø, southern Norway. The mussels had green spots in their mantle tissues, mainly posteriorly and ventrally, and in the ... -

Population dynamics of salmon lice Lepeophtheirus salmonis on Atlantic salmon and sea trout
(Journal article; Peer reviewed, 2005-04-13)The salmon louse Lepeophtheirus salmonis is a common ectoparasite of both farmed and wild salmonids in the marine environment, and can have a significant negative effect on the survival and growth of its host. To facilitate ... -
Overvåking av forurensningsituasjonen i indre Oslofjord 2004 [Fagrådsrapport nr. 97]
(NIVA-rapport;OR-5024, Research report, 2005-05-30)Rapporten omhandler resultatene fra undersøkelser foretatt i indre Oslofjord hovedsakelig i 2004. Dypvannsfornyelsen var god i Vestfjorden, men beskjeden i Bunnefjorden. Oksygenforholdene har blitt bedre i Vestfjorden siden ...
